Specification of Letters Patent.

Patented April 21, 1908.

Application led September 23, 1907. Serial No. 394,195.

To all whom 'it may concern: Y

Be it known that we, JOSEPH STREET and JOSHUA H. SlR1 11i:T,-citizens ofthe United States, residing at Chattanooga, in the county of Hamiltonand State of Tennessee, have invented certain new and usefulImprovements in Shingle and Headin iMachines, of which the following isa specication.

This invention relates to the mechanism in a shingle and heading machinefor sup orting and adjusting the'cradle upon which t e timber-bolt isreceived after each sawing and is re-set for the next cu In theaccompanying drawings which illustrate our invention-Figure 1 isa viewvin side elevation of ya machine embodying our.

invention, a part ofthe machine being broken away to illustrate theparts beyond. Fig. 2 is a detail in elevation, viewed from the oppositeside of the machine from that shown in Fig. 1, and Fig. 3 is a view inend elevation of the parts shown in Fig. 2 looking in the direction ofthe arrow in said Fig. 2.

Like characters of reference indicate like parts throughout the severalviews of the drawing.

4 represent the two end frames of the machine which are connected bymeans of the six horizontal shafts 5 and 6 arranged in triplicate oneach side of the machine. Of these, the top shafts 6 form a track forthe carriage 7 which holds and carries the material, that is thetimber-bolt, which is to be sawed into shingles or heading. Thiscarriage 7 may be of any suitable .construction such for example as isshown and described in our application for patent` for shingle andheading machine, filed October 4, 1906, Serial No. 337,464.

9 is a circular saw mounted at one end of the machine frame in ahorizontaly plane below the carriage 7 and the timber-bolt which is heldby the carriage is brought into contact with the saw b'y the movementofthe carriage longitudinally of the shafts 6, toward After each shingleor heading is removed from the timber-boltby the saw the carriage 7 isreturned to the position shown. in Fig. 1, whereupon the timber-bolt isreleased by a swinging movement of the lever 8, and drops by gravitydown upon the cradle 10. The distance of the cradle 10 below the lane ofsaw 9 determines the thickness of t e shingle or heading removed bythesaw, and the angular adjustment of the cradle 10 with relation to theplane of the saw 9 4for the arm 12. The

timber-bolt Vis of thicker at one edge and it determines the amount ofvariance between the thicknesses4 of the said edges.

The meansfor supporting the'cradle and for'determining its adjustmentare of the essence of this invention and will now be described.

11is a bracket which is bolted to the end 4 of the machine frameopposite that end of said frame in which saw 9 is mounted and 12 is anadjustable extension or arm of the bracket 11. Itis pivotally secured orhinged vto the bracket 11 by means of the bolt 13. 'The bracket 11 has alateral lug 14 with a screw-threaded vertical hole in which the setscrew 15 isoperated so as` to form a bearing arm 12 rests upon the upperend of the set screw 15, and-the outer or ree end of the arm 12 israised or lowered by correspondingly screwing the set screw toward orfrom said arm, and any given adjustment will be retained by means of thelock-nut 16.

17 is a cradle-base having four arms arranged in two pairs at rightangles toeach other. One pair of these arms has the vertically extendedend ears 18, between lwhich ears the cradle 10 is pivotally secured bymeans of the bolts orscrews 19. The screws 19 havelock-'nuts 20 to keepthe screws from working loose by a rocking movement of the cradle. Thecradle 10 will be tilted or rocked on the set screws 19 within certainlimits which will be prescribed by the set screws 21.

The set screws 21 pass up through the ends of the other pair of armsofthe cradle-base 17, and the vertically moving lower ed es of thecradle 10 are adapted to contact wit the upper ends of one or the .otherof said set screws 21 at each rocking movement or tilt of said cradle,and the extent of the tilt of the cradle will be determined by theamount of extension above the cradle-base of said set screws 21. It isobvious that both set screws 21 may be screwed into contact with thebottom of cradle 10 so as to altogether prevent the rocking or tilt ofthe cradle, and these screws can be so adjusted as to bring both tracks24 of the cradle in a plane parallel with the plane of the saw 9 so thatthe section removed by the saw from the timberbolt Will be of uniformthickness. It is also obvious that by lowering the upper ends of setscrews 21 from the position last described determines whether the piecesawed off of the the cradle will be allowed to tilt in directproportion, subject to the limitations of the device. Lock-nuts 22 areJfor the purpose oi holding any given adjustment of the set screws 21.

Depending Jfrom the cradle-base 17 and formed as an integral part ofsaid cradlebase is the clamping-plate 26 through which a transverse holeis formed for the reception of the bolt 27. This bolt 27 also passesthrough a vertical slot 29 in the end oi the arm 12. This slotted end ofthe arm 12 is elongated vertically into a flat head for the purpose ofincreasing the clamping surface to contact with the clamping-p ate 26.In order to prevent a rotary movement oi the cradle-base 17 around thebolt 27, the expanded head of the arm 12 is provided, on the side whichcontacts with plate 26, with the rib extension 30, which makes a closesliding fit in a corresponding channel or groove in the plate 26.

vAt the lower end or' the rib 30 is the lug 32 whichextends in a lateraldirection toward the plate 26, and is provided with a verticalscrew-threaded. hole to receive the set screw 33. The latter afterpassing through the lug V32 bears against the lower edge of theclamping-plate 26 and provides a means for carefully adjusting theposition of said late 26 with relation to the head in the end oi arm 12.This adjustment raises and lowers the Y cradle-base and also the cradle10 which is carried by said base. The lock-nut 35 enables a givenadjustment to be retained. A flange 37 adjacent to and parallel withslot 29 serves as a lock to prevent the rotation of bolt 27 in saidslot.

The jointing of the arm 12 to bracket 11 enables the cradle-base 17 tobe placed in a horizontal or parallel position with relation to theplane of the saw, and this position will be retained by means of the setscrew 16. Then the proper distance of the cradle below the plane orc thesaw 9 will be secured by means of the set screw 33.` The tilt of thecradle will be determined by the set screws 21, as has been alreadydescribed.

The cradle 10 will be tilted by hand in the proper direction each timethat the carriage is drawn back.

Having thus fully described our invention what we claim as new and wishto secure by Letters Patent of the United States, is
